Casey is 18 years old and Ralph is 3 years old.
Step-by-step explanation:
Let,
Age of Casey = x
Age of Ralph = y
According to given statement;
x = 6y Eqn 1
In two years
x+2=4(y+2)
x+2=4y+8
x = 4y+8-2
x = 4y+6 Eqn 2
Putting value of x from Eqn 1 in Eqn 2

Dividing both sides by 2

Putting y=3 in Eqn 1

Casey is 18 years old and Ralph is 3 years old.

<h2>circumference = 50.24cm</h2><h2>area = 200.96cm²</h2>
Step-by-step explanation:
radius (r) = 8cm
circumference = 2π×r
= 2 × 3.14 × 8
= 50.24cm
area = π × r²
= 3.14 × 8 × 8
= 200.96cm²
